PRODUCT USE INFORMATION
Certain Rough Country Suspension products especially long arm kits are intended to improve off-road
performance. The addition of this kit may result in the vehicle handling differently than a factory equipped vehicle. As a
rule seat belts and shoulder harnesses should be worn at all times. Avoid situations where a side rollover may occur.
Generally, braking performance and capability are decreased when larger/heavier tires and wheels are used. Take this
into consideration while driving.
Do not add, alter, or fabricate any factory or after-market parts to increase vehicle height over the intended height of the
Rough Country product purchased. Mixing component brands is not recommended.
Rough Country makes no claims regarding lifting devices and excludes any and all implied claims. We will not be re-
sponsible for any product that is altered.
This kit features Rough Country’s adjustable joint design. Adjustable end tool is included in kit.
Assemble the joints per the separate instruction sheet Part # 92RCJ120 provided.
Due to inconsistency of vehicles when manufactures and various options available, the amount of actual lift gained by
this lift kit could vary. Muffler modification or off-road mufflers are required on this kit.
This suspension system was developed using a 31 x 10.50 x 15 tire with factory wheels. After market wheel will fit with
3 5/8” back spacing. Larger tire and wheel combinations may increase leverage on suspension, steering and related
components. Consider the additional stress you could be adding on the OE components, when selecting combinations
larger than OE. NOTICE TO DEALER AND VEHICLE OWNER
Any vehicle equipped with any Rough Country product should have a “Warning to Driver” decal installed on the inside of
the windshield or on the vehicle’s dash. The decal should act as a constant reminder for whoever is operating the vehi-
cle of its unique handling characteristics.
